Generation of selenium hydride from alkaline solutions: a new concept of the hydride generation-atomic absorption technique

摘要

The use of hydride generation is often useful in environmentalanalysis. The normal acid sodium tetrahydroborate reactionprovides exceptional sensitivity with continuous flow hydridegenerators. In some situations there are interferences which willmask the sensitivity. An alternative chemistry system is describedhere and is shown to offer similar sensitivity to that normally used.A commercial continuous flow analyser is used in this work.
